Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization, and particularly relates to an atomizer, a power supply host and an electronic atomization device. Background Art

[0002] Electronic cigarettes and electronic devices for atomizing health care drugs, therapeutic drugs and other substances can be collectively referred to as electronic atomization devices. An electronic atomization device generally includes an atomizer for generating aerosol and a power supply host for providing electrical energy to the atomizer. According to whether the atomizer can be replaced, the electronic atomization device can be divided into a disposable electronic atomization device and a cartridge-replaceable electronic atomization device. Among them, the cartridge-replaceable electronic atomization device generally adopts a design in which the atomizer and the power supply host are detachably connected. When the atomizable substance in the atomizer is consumed, only a new atomizer needs to be replaced to repeat the use, without discarding the power supply host. Therefore, compared with the disposable electronic atomization device, it is beneficial to reduce the user's usage cost.

[0003] However, in most of the cartridge-replaceable electronic atomization devices on the market at present, a liquid storage cavity for storing atomization liquid (such as e-liquid) is usually formed inside the atomizer, and an atomization core for heating and atomizing the atomization liquid is provided. Since the liquid storage cavity is generally filled with atomization liquid when the atomizer leaves the factory, the overall mass of the atomizer is increased, thereby increasing the transportation cost of the atomizer.

[0037] To achieve the above object, the present utility model further provides a power supply host, which is used for being assembled and used with an atomizer in any of the above-mentioned embodiments of the electronic atomization device, and the power supply host is the power supply host in any of the above-mentioned embodiments of the electronic atomization device.

[0038] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0039] In the technical solution of the present utility model, the electronic atomization device includes a power supply host and an atomizer. The power supply host is provided with a receiving cavity and respectively has an opening on two opposite side surfaces of the power supply host. The atomizer is detachably installed in the receiving cavity through the opening. The atomizer includes a first housing, a second housing, and an atomization core. A first liquid storage cavity and a first air passage are formed in the first housing. The first housing is detachably connected to the second housing, and the atomization core is communicated with the first liquid storage cavity. Since the atomizer includes a first housing and a second housing that are detachably connected, the first housing has a first liquid storage cavity for storing atomization liquid, and the second housing does not store atomization liquid. Moreover, the volume of the atomization liquid in the first liquid storage cavity of the first housing is less than the overall volume of the atomizer (i.e., the sum of the volumes of the first housing and the second housing). Therefore, during the transportation of the atomizer, even if the first liquid storage cavity of the first housing is filled with atomization liquid, the overall mass of the atomizer (including the mass of the first housing storing the atomization liquid and the second housing not storing the atomization liquid) will be much lighter than the overall mass of the atomizer filled with atomization liquid (including the masses of the first housing and the second housing both storing the atomization liquid). In this way, the transportation cost of the atomizer can be saved.

[0040] In addition, since the atomizer includes a first housing and a second housing that are detachably connected, the overall volume of the first housing is less than or equal to the overall volume of the second housing, and the volume of the receiving cavity of the power supply host is greater than the overall volume of the first housing. Therefore, in the application scenario where the atomizer is installed in the receiving cavity of the power supply host through the opening, by setting the second housing, the first housing with a smaller overall volume can be stably installed in the receiving cavity of the power supply host. This can not only prevent the first housing from moving axially along the power supply host and separating from the bottom wall of the receiving cavity, resulting in the first air passage in the first housing being unable to communicate with the air passage of the host power supply, but also prevent the first housing from falling out of the receiving cavity of the host power supply.

[0062] Reference Figures 1 to 3 、 Figure 7 and Figure 8 The embodiment of the present invention provides an electronic atomization device, comprising a power supply main unit 100 and an atomizer 200. The power supply main unit 100 is provided with a accommodating chamber 110, and an opening 120 is respectively provided on two opposite sides of the power supply main unit 100. The atomizer 200 is detachably mounted in the accommodating chamber 110 through the opening 120. The atomizer 200 comprises a first shell 210, a second shell 220 and an atomizer core 230. A first liquid storage chamber 211 and a first air passage 213 are formed in the first shell 210. The first shell 210 and the second shell 220 are detachably connected, and the atomizer core 230 is communicated with the first liquid storage chamber 211.

[0063] In this embodiment, the atomizer core 230 can be disposed within the first air passage 213 and communicate with the first liquid storage chamber 211. Of course, in other embodiments, the atomizer core 230 can also be disposed at the bottom of the first liquid storage chamber 211 and below the first air passage 213. In this case, the bottom of the first liquid storage chamber 211 can be provided with at least one through-hole for conducting atomized liquid. The atomizer core 230 is disposed corresponding to the through-hole disposed at the bottom of the first liquid storage chamber 211. In this way, the atomizer core 230 can communicate with the first liquid storage chamber 211 through the through-hole.

[0064] In specific implementation, in some application scenarios of assembling an electronic atomization device, the first housing 210 can be detachably connected to the second housing 220 by means of clearance fit, transition fit, etc., and then the interconnected first housing 210 and second housing 220 can be detachably inserted into the accommodation cavity 110 of the power supply host 100 through the opening 120 by means of clearance fit, transition fit, etc., thus completing the assembly of the electronic atomization device, which is very convenient. In addition, in some application scenarios of replaceable atomizers 200, it is only necessary to remove the atomizer 200 (i.e., the first housing 210 and the second housing 220) from the opening 120, and then replace the first housing 210, and the whole process is also very convenient.

[0065] It should be noted that the above two openings 120 can be opened on the front and back of the power supply host 100, or can be opened on the left and right sides of the power supply host 100. In this way, the atomizer 200 can be inserted into the accommodation cavity 110 of the power supply host 100 through any one of the openings 120, or can be removed from the accommodation cavity 110 of the power supply host 100 through any one of the openings 120. Among them, as shown in Figure 2 and Figure 7 In this embodiment, the two openings 120 (i.e., the first opening 1201 and the second opening 1202) are provided on the front and back of the power supply host 100. Compared with the scheme of setting on the left and right sides, it can achieve the purpose of being more convenient for users to disassemble and assemble.

[0066] In this embodiment, based on the above structural design, since the atomizer 200 includes a first housing 210 and a second housing 220 that are detachably connected, the first housing 210 has a first liquid storage cavity 211 for storing atomization liquid, the second housing 220 does not store atomization liquid, and the volume of the atomization liquid in the first liquid storage cavity 211 of the first housing 210 is less than the overall volume of the atomizer 200 (i.e., the sum of the volumes of the first housing 210 and the second housing 220). Therefore, during the transportation of the atomizer 200, even if the first liquid storage cavity 211 of the first housing 210 is filled with atomization liquid, the overall mass of the atomizer 200 (including the mass of the first housing 210 storing atomization liquid and the second housing 220 not storing atomization liquid) will be much lighter than the overall mass of the atomizer 200 filled with atomization liquid (including the mass of the first housing 210 and the second housing 220 both storing atomization liquid). In this way, the transportation cost of the atomizer 200 can be saved.

[0067] In addition, since the atomizer 200 includes a first housing 210 and a second housing 220 that are detachably connected, the overall volume of the first housing 210 is less than or equal to the overall volume of the second housing 220, and the volume of the accommodation cavity 110 of the power supply main unit 100 is greater than the overall volume of the first housing 210. Therefore, in the application scenario where the atomizer 200 is installed in the accommodation cavity 110 of the power supply main unit 100 through the opening 120, by setting the second housing 220, the first housing 210 with a smaller overall volume can be stably installed in the accommodation cavity 110 of the power supply main unit 100, which can not only prevent the first housing 210 from moving axially along the power supply main unit 100 and disengaging from the bottom wall of the accommodation cavity 110, resulting in the first air passage 213 in the first housing 210 being unable to communicate with the air passage of the main unit power supply 100, but also prevent the first housing 210 from falling out of the accommodation cavity 110 of the main unit power supply 100.

[0068] Furthermore, as Figure 3 and Figure 8 shown, a second air passage 221 communicating with the outside is provided in the second housing 220. When the first housing 210 is connected to the second housing 220, the first air passage 213 communicates with the second air passage 221. Thus, in the application scenario where the atomizer 200 is installed in the accommodation cavity 110 of the power supply main unit 100 through the opening 120, the first air passage 213 communicates with the second air passage 221 to form an air flow passage of the atomizer 200, and this air flow passage communicates with the air passage on the power supply main unit 100, thereby ensuring the normal use of the electronic atomization device.

[0069] Furthermore, in combination with Figures 1 to 3 , Figures 5 to 9 shown, a mouthpiece 130 communicating with the accommodation cavity 110 is further provided at one end of the power supply main unit 100. The second air passage 221 of the second housing 220 has an air inlet port 2211 and an air outlet port 2212, and the air outlet port 2212 communicates with the mouthpiece 130. An installation groove 222 is provided at one end of the second housing 220 close to the air inlet port 2211 (as Figure 5 and Figure 9 ), the first housing 210 is detachably inserted into the installation groove 222, and the first air passage 213 in the first housing 210 communicates with the air inlet port 2211. Thus, the first air passage 213 in the first housing 210 communicates with the air inlet port 2211 of the second air passage 221 in the second housing 220, and the air outlet port 2212 of the second air passage 221 remains in communication with the mouthpiece 130. When the user sucks through the mouthpiece 130, outside air will first enter the first air passage 213 and mix with the aerosol generated after being heated and atomized by the atomization core 230 in the first air passage 213 to form a suction air flow, and then the suction air flow flows out to the outside through the air inlet port 2211 of the second air passage 221, the air outlet port 2212 of the second air passage 221, and the mouthpiece 130 for the user to inhale.

[0070] In this embodiment, the nozzle 130 and the power supply host 100 are of an integral structure, so that in the exemplary technology of the replaceable cartridge type electronic atomization device, the nozzle 130 will not be replaced as the atomizer 200 is replaced, which can avoid waste of the nozzle 130 and is beneficial to reducing the user's usage cost.

[0071] Further, in order to ensure the connection between the first air passage 213 and the air inlet port 2211 of the second air passage 221, in this embodiment, in combination with Figure 2 , Figure 3 , Figure 5 , Figures 7 to 9 As shown in, on the groove wall of the installation groove 222 close to the air inlet port 2211 of the second air passage 221, there is a plug hole 2221, and the plug hole 2221 is connected to the air inlet port 2211 of the second air passage 221. One end face of the first housing 210 close to the air inlet port 2211 of the second air passage 221 is convexly provided with a hollow plug portion 214, and the internal space of the plug portion 214 is connected to the first air passage 213. The plug portion 214 is inserted into the plug hole 2221 so that the first air passage 213 is connected to the air inlet port 2211 of the second air passage 221 through the plug portion 214. It should be noted that the outer peripheral wall of the plug portion 214 is in close contact with the hole wall of the plug hole 2221, so as to ensure the airtightness between the first air passage 213 and the air inlet port 2211 of the second air passage 221 and prevent air leakage when the user sucks.

[0072] In this embodiment, in order to further ensure the airtightness between the first air passage 213 and the air inlet port 2211 of the second air passage 221, at least one sealing ring made of a sealing material such as rubber or silica gel can be provided on the outer peripheral wall of the plug portion 214 or on the hole wall of the plug hole 2221.

[0073] Further, in combination with Figure 2 , Figure 3 , Figure 5 , Figures 7 to 9As shown in the figure, a first limiting portion 215 is provided on the outer wall of the first housing 210, and a second limiting portion 2223 is provided on the wall of the installation groove 222. The first limiting portion 215 is engaged with the second limiting portion 2223. In this way, by means of the engagement between the first limiting portion 215 and the second limiting portion 2223, the first housing 210 can be stably retained in the installation groove 222 of the second housing 220 after being inserted into the second housing 220, preventing the first housing 210 from accidentally coming out of the installation groove 222 of the second housing 220 and affecting the user experience. Moreover, when it is necessary to remove the first housing 210 from the installation groove 222 of the second housing 220, just hold the first housing 210 and the second housing 220 simultaneously and apply forces in opposite directions to the first housing 210 and the second housing 220 to release the engagement between the first limiting portion 215 and the second limiting portion 2223, so that the first housing 210 can be quickly removed from the installation groove 222 of the second housing 220, which is very convenient.

[0074] In this embodiment, in specific implementation, in some alternative implementation manners, the specific setting manners of the first limiting portion 215 and the second limiting portion 2223 can be as follows:

[0075] Specifically, please refer to Figure 2 、 Figure 3 、 Figure 5 、 Figures 7 to 9 that the first limiting portion 215 includes at least one hook 2151 provided on the outer wall of the first housing 210, and the second limiting portion 2223 includes at least one slot 22231 provided on the wall of the installation groove 222. Each hook 2151 is engaged with each slot 22231 one by one, so as to realize the engagement between the first housing 210 and the second housing 220, and enable the first housing 210 to be stably retained in the installation groove 222 of the second housing 220 after being inserted into the installation groove 222 of the second housing 220, preventing the first housing 210 from accidentally coming out of the installation groove 222 of the second housing 220 and affecting the user experience.

[0076] In some other alternative implementation manners, the specific setting manners of the first limiting portion 215 and the second limiting portion 2223 can also be as follows:

[0077] Specifically, the first limiting portion 215 includes at least one card slot (not shown) provided on the outer wall of the first housing 210, and the second limiting portion 2223 includes at least one catch (not shown) provided on the wall of the installation groove 222. Each catch is in one-to-one snap connection with each card slot, so as to realize the snap connection between the first housing 210 and the second housing 220, so that the first housing 210 can stably stay in the installation groove 222 of the second housing 220 after being inserted into the installation groove 222 of the second housing 220, avoiding the accidental detachment of the first housing 210 from the installation groove 222 of the second housing 220 and affecting the user experience.

[0078] Further, referring to Figure 3 As shown, a cavity 223 is further provided in the second housing 220. The cavity 223 is separated from the first air passage 221 and is a closed cavity. As described above, if no atomizing liquid is injected into the cavity 223 in the second housing 220, then when the atomizer 200 is in the transportation state, the mass of the second housing 220 can be reduced, making the overall mass of the atomizer 200 very light, so as to save the transportation cost of the atomizer 200.

[0079] Further, in some usage scenarios of the atomizer 200, referring to Figure 4 As shown, the cavity 223 can also be a second liquid storage cavity 224 for storing atomizing liquid. Specifically, when the atomizing liquid in the first liquid storage cavity 211 is consumed, the first housing 210 can be detached from the installation groove 222 of the second housing 220, and then the first housing 210 can be inserted into the installation groove 222 of a new second housing 220. Among them, the second liquid storage cavity 224 of the new second housing 220 stores atomizing liquid. In this way, the atomizing liquid in the new second housing 220 will flow into the first liquid storage cavity 211 for the atomizing core 230 to continue heating and atomizing.

[0080] Further, since the volume in the first liquid storage cavity 211 of the first housing 210 (i.e., the liquid storage capacity of the atomizer 200) is generally fixed, in order to meet the laws and regulations in some regions, for example, the laws and regulations in the European region require that the liquid storage capacity of the sold atomizer 200 cannot exceed 2 ml. In this embodiment, the volume of the first liquid storage cavity 211 of the first housing 210 does not exceed 2 ml. That is, assuming the volume of the first liquid storage cavity 211 is V1, then V1 ≤ 2 ml. In this way, not only can the liquid storage capacity of the atomizer 200 meet the laws and regulations in the European region, but also the overall mass of the atomizer 200 can be reduced, thereby effectively reducing the transportation cost of the atomizer 200.

[0081] Since the volume of the above-mentioned first liquid storage cavity 211 is small, in this embodiment, the cavity 223 of the second housing 220 is set as a second liquid storage cavity 224 that can store the atomization liquid, and the volume of the second liquid storage cavity 224 is greater than or equal to the volume of the first liquid storage cavity 211. Assuming the volume of the second liquid storage cavity 224 is V2, the relationship between V1 and V2 can be the following two setting relationships:

[0082] In some embodiments, V2 / V1≥1, that is, the ratio of the volume V2 of the second liquid storage cavity 224 to the volume V1 of the first liquid storage cavity 211 is greater than or equal to 1. For the convenience of understanding, assuming the volume V1 of the first liquid storage cavity 211 is 2 ml, then the volume V2 of the second liquid storage cavity 224 is greater than or equal to 2 m, that is, V2≥2 ml. In this way, by setting the ratio of the volume V2 of the second liquid storage cavity 224 to the volume V1 of the first liquid storage cavity 211 to be greater than or equal to 1, there are the following several advantages:

[0083] First, compared with the scheme in which only the first liquid storage cavity 211 in the first housing 210 of the atomizer 200 stores the atomizer, the overall liquid storage capacity of the atomizer 200 can be expanded without changing the volume of the first liquid storage cavity 211, so that the atomizer 200 can provide more puff numbers for users and meet the puff experience of users;

[0084] Second, since the overall liquid storage capacity of the atomizer 200 is improved, the operation of the user to replenish the atomization liquid multiple times due to the consumption of the atomization liquid in the first liquid storage cavity 211 is reduced. Furthermore, the number of times the user replenishes the atomization liquid in the first liquid storage cavity 211 can be effectively reduced, which is beneficial to improving the user experience;

[0085] Third, since the liquid storage capacity in the first liquid storage cavity 211 is limited (the factory setting is generally 2 ml), when the atomization liquid in the first liquid storage cavity 211 is consumed, the service life of the atomization core 230 provided in the first housing 210 has not reached the limit yet. At this time, if the first housing 210 is discarded, it will cause waste of the atomization core 230. In this embodiment, after the atomization liquid in the first liquid storage cavity 211 is consumed, the atomization liquid stored in the second liquid storage cavity 224 can be replenished to the first liquid storage cavity 211, so that the atomization core 230 can continue to be used, thereby avoiding waste of the atomization core 230 caused by being discarded before the service life of the atomization core 230 reaches the limit, and then improving the utilization rate of the atomization core 230 and reducing the user's usage cost.

[0086] In some other embodiments, V2 / V1≥5, that is, the ratio of the volume V2 of the second liquid storage cavity 224 to the volume V1 of the first liquid storage cavity 211 is greater than or equal to 5. For the convenience of understanding, assume that the volume V1 of the first liquid storage cavity 211 is 2 ml, then the volume V2 of the second liquid storage cavity 224 is greater than or equal to 10 ml, that is, V2≥10 ml. Compared with the above embodiments where V2 / V1≥1, in this embodiment, by setting V2 / V1≥5, not only can the number of puffs of the user be greatly increased, so as to better meet the user's puffing experience, but also the number of times the user replenishes the atomizing liquid in the first liquid storage cavity 211 can be further reduced, which is more conducive to improving the user's usage experience. At the same time, the utilization rate of the atomization core 230 can be further increased, thereby further reducing the user's usage cost.

[0087] [[ID=③]]In addition, in this embodiment, when V2 / V1≥5, the volume of the first liquid storage cavity 211 on the first housing 210 is much smaller than the volume of the second liquid storage cavity 224 on the second housing 220. Thus, when the atomizer 200 is in the transportation state, since the atomizing liquid that can be stored in the first liquid storage cavity 211 of the first housing 210 is very little (generally not exceeding 2 ml) and the second liquid storage cavity 224 of the second housing 220 does not store atomizing liquid, therefore, the volume occupied by the atomizing liquid in the first liquid storage cavity 211 is much smaller than the overall volume of the atomizer 200, so that the overall mass of the atomizer 200 can be greatly reduced, and thus the transportation cost of the atomizer 200 can be further saved.

[0088] It should be noted that when V1 = 2 ml, V2 = 10 ml and the atomizing liquids in both the second liquid storage cavity 224 and the first liquid storage cavity 211 are consumed, the service life of the atomization core 230 also basically reaches the limit. At this time, only need to remove the atomizer 200 from the opening 120 and replace it with a new atomizer 200 to continue using. In addition, since the service life of the atomization core 230 also basically reaches the limit after the atomizing liquids in the first liquid storage cavity 211 and the second liquid storage cavity 224 are consumed, therefore, the atomizer 200 can be discarded, that is, both the first housing 210 and the second housing 220 can be discarded. At this time, the second housing 220 and the first housing 210 can be fixedly connected.

[0089] Furthermore, referring to Figures 7 to 9 as shown, in specific implementation, the atomizing liquid in the second liquid storage cavity 224 can be replenished into the first liquid storage cavity 211 in the following manner:

[0090] At least one liquid outlet hole 2241 is formed at one end of the second liquid storage cavity 224 close to the air inlet port 2211 of the second air passage 221. A seal 2242 is provided on the liquid outlet hole 2241. At least one hollow piercing member 216 protrudes from the end face of the first housing 210 close to the air inlet port 2211 of the second air passage 221. The internal space of the piercing member 216 communicates with the first liquid storage cavity 211. The piercing member 216 passes through the seal 2242 and extends into the second liquid storage cavity 224, so that the second liquid storage cavity 224 communicates with the first liquid storage cavity 211 through the piercing member 216. In this way, the atomized liquid in the second liquid storage cavity 224 can be replenished into the first liquid storage cavity 211 through the piercing member 216 for the atomizing core 230 to heat and atomize.

[0091] In this embodiment, in order to facilitate the piercing member 216 to pierce the seal 2242, the end of the piercing member 216 away from the first housing 210 is a tip. It should be noted that the above tip can be a leaf tip shape, a serrated shape or other structures convenient for piercing the seal 2242, and specific limitations are not made here.

[0092] Furthermore, the seal 2242 is a sealing film, and the sealing film is sealed at one end of the liquid outlet hole 2241 located in the second liquid storage cavity 224, or the sealing film is sealed at one end of the liquid outlet hole 2241 located in the mounting groove 222. In this way, on the one hand, it can prevent the atomized liquid in the second liquid storage cavity 224 from leaking when the second housing 220 is in a non-use state (such as the transportation state or the state when not inserted with the first housing 210); on the other hand, it can prevent dust particles or other types of particles from entering the second liquid storage cavity 224 through the liquid outlet hole 2241, resulting in the contamination of the atomized liquid in the second liquid storage cavity 224.

[0093] Furthermore, in order to prevent the atomized liquid in the second liquid storage cavity 224 from leaking between the piercing member 216 and the liquid outlet hole 2241, in this embodiment, the outer peripheral wall of the piercing member 216 is in close contact with the hole wall of the liquid outlet hole 2241. Of course, it should be noted that a sealing ring made of a sealing material such as rubber or silica gel can also be provided on the outer peripheral wall of the piercing member 216 or the hole wall of the liquid outlet hole 2241. In this way, the effect of preventing the atomized liquid from leaking between the piercing member 216 and the liquid outlet hole 2241 can also be achieved.

[0094] Furthermore, based on the above embodiment, refer to Figure 2 and Figure 7As shown, the two openings 120 on the power supply main unit 100 include a first opening 1201 and a second opening 1202 that are oppositely arranged along the thickness direction of the power supply main unit 100. The first opening 1201 and the second opening 1202 can both be in a closed ring shape. For example, the shapes of the first opening 1201 and the second opening 1202 can both be in closed ring shapes such as rectangles, squares, trapezoids, regular hexagons, etc., which can be determined according to actual needs. For example, when the overall shape of the atomizer 200 is a cuboid, the first opening 1201 and the second opening 1202 of the power supply main unit 100 can both be rectangles. In this embodiment, there is no specific limitation on the specific shapes of the first opening 1201 and the second opening 1202, as long as the usage requirements can be met.

[0095] It should be noted here that in specific implementations, the specific shape of the first opening 1201 and the specific shape of the second opening 1202 can be the same or different, and this embodiment does not make specific limitations on this.

[0096] In some embodiments, such as Figure 2 and Figure 7As shown, the power supply main body 100 further has a limiting flange 140 disposed around the first opening 1201. The first housing 210 has a first end face 217, and the second housing 220 has a second end face 225. A first limiting frame 2171 is disposed on the outer edge of the first end face 217, and a second limiting frame 2251 is disposed on the outer edge of the second end face 225. When the first housing 210 and the second housing 220 are connected to each other and are installed in the accommodation cavity 110 of the power supply main body 100 through the first opening 1201, the first limiting frame 2171 abuts against the limiting flange 140, and the second limiting frame 2251 abuts against the limiting flange 140. Moreover, both the first end face 217 and the second end face 225 are disposed close to the first opening 1201. With such a setting, during the process of inserting and assembling the first housing 210 and the second housing 220 together (i.e., assembling them into a complete atomizer 200) and installing them in the accommodation cavity 110 of the power supply main body 100, it can be ensured that the atomizer 200 can be installed in place. That is to say, during the process of installing the atomizer 200 into the accommodation cavity 110 of the power supply main body 100 through the first opening 1201, when the first limiting frame 2171 of the first housing 210 and the second limiting frame 2251 of the second housing 220 respectively abut against the limiting flange 140, it indicates that the atomizer 200 has been installed in place, thereby avoiding the situation where the second air passage 221 and the nozzle 130 cannot be communicated due to the atomizer 200 not being installed in place. It should be noted that in some application scenarios of disassembling the atomizer 200, since there is no limiting structure at the second opening 1202, that is, when disassembling the atomizer 200, a force can be applied to the atomizer 200 from the second opening 1202, so that the atomizer 200 moves in the direction of the first opening 1201, and the atomizer 200 can be disassembled from the accommodation cavity 110 of the power supply main body 100, which is very convenient.

[0097] In other embodiments, the power supply main body 100 further has a limiting flange 140 disposed around the second opening 1202. The first housing 210 has a first end face 217, and the second housing 220 has a second end face 225. A first limiting frame 2171 is disposed on the outer edge of the first end face 217, and a second limiting frame 2251 is disposed on the outer edge of the second end face 225. When the first housing 210 and the second housing 220 are connected to each other and are installed in the accommodation cavity 110 of the power supply main body 100 through the second opening 1202, the first limiting frame 2171 abuts against the limiting flange 140, and the second limiting frame 2251 abuts against the limiting flange 140. Moreover, both the first end face 217 and the second end face 225 are disposed close to the second opening 1202. In this embodiment, the effect of ensuring that the atomizer 200 is installed in place can also be achieved. For details, reference can be made to the above description, and no further elaboration will be provided here.

[0098] Further, in combination with Figure 2 、 Figure 6 andFigure 7 As shown, a third limiting portion 226 is provided at one end of the second housing 220 away from the first housing 210, and a fourth limiting portion 112 adapted to the third limiting portion 226 is provided on the cavity wall of the accommodating cavity 110. The third limiting portion 226 is snap-fitted with the fourth limiting portion 112. In this way, by the snap-fitting action between the third limiting portion 226 and the fourth limiting portion 112, the second housing 220 can be stably retained in the accommodating cavity 110 of the power supply main body 100 after being inserted into the accommodating cavity 110 of the power supply main body 100, preventing the second housing 220 from accidentally disengaging from the accommodating cavity 110 of the power supply main body 100 during the use of the electronic atomization device by the user and affecting the user experience.

[0099] It should be noted that the third limiting portion 226 includes at least one first limiting protrusion 2261 provided at one end of the second housing 220 away from the first housing 210 (such as Figure 2 and Figure 7 ), and the fourth limiting portion 112 includes at least one first limiting groove 1121 provided on the cavity wall of the accommodating cavity 110 (such as Figure 6 ), and each first limiting protrusion 2261 is snap-fitted with each first limiting groove 1121 one by one. In this embodiment, the number of the first limiting protrusions 2261 and the first limiting grooves 1121 can be one or more, which can be specifically set according to actual needs and are not limited herein.

[0100] Furthermore, as shown in Figure 2 , Figure 4 and Figure 7 , a fifth limiting portion 218 is provided at one end of the first housing 210 away from the second housing 220, and a sixth limiting portion 113 adapted to the fifth limiting portion 218 is provided on the cavity wall of the accommodating cavity 110. The fifth limiting portion 218 is snap-fitted with the sixth limiting portion 113. In this way, by the snap-fitting action between the fifth limiting portion 218 and the sixth limiting portion 113, the first housing 210 can be stably retained in the accommodating cavity 110 of the power supply main body 100 after being inserted into the accommodating cavity 110 of the power supply main body 100, preventing the first housing 210 from accidentally disengaging from the accommodating cavity 110 of the power supply main body 100 during the use of the electronic atomization device by the user and affecting the user experience

[0101] It should be noted that the fifth limiting portion 218 includes at least one second limiting protrusion 2181 provided at one end of the first housing 210 away from the second housing 220 (such as Figure 4 ), and the sixth limiting portion 113 includes at least one second limiting groove 1131 provided on the cavity wall of the accommodating cavity 110 (such as Figure 2 and Figure 7) Each second limiting protrusion 2181 is in snap fit with each second limiting groove 1131 one by one. In this embodiment, the number of the second limiting protrusions 2181 and the second limiting grooves 1131 can be one or more, which can be specifically set according to actual requirements and are not limited herein.

[0102] Furthermore, in combination with Figure 2 、 Figure 4 and Figure 7 As shown, at least one first sliding part 219 extending in the thickness direction of the power supply main body 100 is provided at one end of the first housing 210 away from the second housing 220, and at least one second sliding part 114 adapted to the first sliding part 219 is provided on the cavity wall of the accommodating cavity 110. Each first sliding part 219 is in sliding fit with each second sliding part 114 one by one. Among them, in specific implementation, in some implementation manners, the structural form of the first sliding part 219 can be a slide rail. Correspondingly, at this time, the structural form of the second sliding part 114 can be a sliding groove; in other implementation manners, the structural form of the first sliding part 219 can also be a sliding groove. Correspondingly, at this time, the structural form of the second sliding part 114 can be a slide rail, as long as the use requirements can be met. This embodiment does not make specific limitations on this. Exemplarily, as Figure 4 shown, the structural form of the first sliding part 219 is a slide rail provided at one end of the first housing 210 away from the second housing 220; as Figure 2 and Figure 7 shown, the structural form of the second sliding part 114 is a sliding groove provided on the cavity wall of the accommodating cavity 110.

[0103] In this embodiment, based on the above structural design, through the sliding fit between the first sliding part 219 and the second sliding part 114, it is beneficial to make the atomizer 200 more smoothly installed into the accommodating cavity 110 of the power supply main body 100 when installing the atomizer 200, and it is beneficial to make the atomizer 200 more smoothly removed from the accommodating cavity 110 of the power supply main body 100 when disassembling the atomizer 200.

[0104] Furthermore, referring to Figure 3 and Figure 8As shown, an intake passage 150 is further provided inside the power supply main body 100. The intake passage 150 has an air inlet 151 and an air outlet 152. The air inlet 151 is located at one end face of the power supply main body 100 away from the suction nozzle 130 and is in communication with the outside. The air outlet 152 is located on the wall of the accommodation chamber 110 and is connected to the first air passage 213. Thus, when the user sucks, the outside air enters the intake passage 150 from the air inlet 151, and then enters the first air passage 213 from the air outlet 152 and is mixed with the aerosol heated and atomized by the atomization core 230 in the first air passage 213 to form a suction air flow. The suction air flow sequentially flows through the first air passage 213, the second air passage 221, and the suction nozzle 130, and is finally inhaled by the user.
